Cadillac spans two very different families: the truck-based Escalade, which shares much with Tahoe and Yukon, and the sedans and crossovers — DeVille, DTS, Seville and STS with the Northstar V8, CTS and ATS on rear-drive platforms, and the SRX and XT5 crossovers. Many of the Cadillac parts we quote are for 1998–2012 DeVille, DTS, CTS and SRX, so we match the part to the exact year, engine and package on your VIN rather than the model name.
What’s different about Cadillac drivetrain and exhaust parts
- Front-drive Northstar cars use front CV axles and a 4T80-E transaxle, while CTS, ATS and the rear-drive STS use a rear differential and, on AWD cars, a transfer case and front axles sold separately by year.
- Escalade AWD uses a full-time transfer case with front CV axles, and the rear axle ratio (3.42 or 3.73) is on the glovebox label; 6.2 catalytic converters are sold per bank and must be CARB-certified for California-emissions trucks.
- Northstar cars carry two catalytic converters and are known for exhaust manifold leaks; CTS 3.6 V6 cars use close-coupled converters built into the manifolds, which makes them costlier than a universal-fit converter.
